OID Indexes

Here are a few simple notes for handling OID indexes. If you want to search on an attribute in OAM where the data is stored in OID it must be indexed. Sometimes you might want to remove and then possible re-add an index. Index adding and removal can be handles with LDIF, however, if you need to recreate an index on existing data then you need to use a command line tool called catalog.

Index an attribute

dn: cn=catalogs
changetype: modify
add: orclindexedattribute
orclindexedattribute: attributename
-

Remove an index

dn: cn=catalogs
changetype: modify
delete: orclindexedattribute
orclindexedattribute: attributename
-

Re-index an attribute
that was previously removed. If you remove an index form an attribute and the data remains and you need to re-index the data in place then you need to use the catalog command line tool.

$ORACLE_HOME/ldap/bin/catalog connect=oiddev add=&quotTRUE" attribute="attributename"

Unwilling to perform
If after the attribute has been re-indexed the directory server will still not allow it to be searched and returns an unwilling to perform error, try restarting the OID gateway.

$ORACLE_HOME/opmn/bin/opmnctl restartproc ias-component=OID

Current Indexed Attirbutes
Use ldapsearch to get the current indexed attributes

ldapsearch -h localhost -p 389 -x -s base -b "cn=catalogs" "objectclass=*"
